The toggle slide 40 is held in position in the key-way 17 by means of the jib 4l, as illustrated in` l*"ig. 3. yThe front end .of .the toggle slide is perforated vto receive'l the spiral spring 42 which rides-on a rod 43 held in position betweenthe shoul der 44 in `the `front end of the housing.

or slide 29 and a hole 45 in the toggle slide "40 in which the rod is loosely fitted. One

of the bifurcations of the extended portion of the link 36 is a flat spring 50 whichopl crates. a pin.v 51 which-,functionsto hold the handle in place when inserted into position between the bifurcations.

'lhe slide or housing 29 is fitted at its front' and rear ends with the downwardly rojecting lus 52, 53, 54, and 55. :These ugs vride inl t e key-ways 16 and 17 respecs tively and are held in position in these keyways by the jibs secured thereto, as illustrated by the jib 56 Secured to the lug 52 illustrated in Fig. 3. Secured to, the ,rear end of the toggle slide 40 is the outwardly projecting arm 57 on whichA is pivotally mounted the lever arm 58'which carries a tooth 59. vThe vlever arm .V58 is under the joint control of a sliding spiral spring 60 and a. catch or dog 61 workin lever 58' in toward the' housing or slide 29,

' and this vmovement of the lever is prevented by the catch 61 which engages lrecesses in 4the member 57,` as indicated in Fig. fl, vand holds said lever out and away from the housing 29. lVhen the catch 6l is thrown'out of enga ement, the lever 58 will movev in toward t e housing and assume the position illustrated by the broken lines in Fig.. 2. The housing. 29 is tted with a series 'of lprojections such as 62, over which the tooth 5 9 Will'ride when the lever 58 is `iineans of the screws 3()4 `and 3l.

in a slot. in the leverarm58. The spira spring 60 is so mounted that it tends'to throw the ing Ais obtained by adjusting t in the broken line position shown in Fig. 2 and the toggle slide is moved to the right in .its slots.

Rigidly secured to the under side of the arm 53 is one end of a cable 63 which eX- tends along the side of the vise and is carriedl over alroller 64 mounted on a stud secured-to the base 10 of the vise. This cable is extended to 'some convenient stud mounted on a stationary part of the machine on which the toggle vise is mounted, as illustrated in Figs. 6 to 9 inclusive and more fully explained hereinafter.

ln assembling the vise the bolt 20 is first put into place by screwing onto the threaded end 2l thereof the tapped portion of the adjusting bar 22. The link 24 is then se cured to the block `23 of the adjusting bar.

-The toggle slide 40 is next fitted into place with its associated spring l2 on the rod 43, the slide being properly positioned by securing the jih 41 thereto. The links and 36 arethen connected to one another,- the link also being pivotally connected to thelink 24 and the link 36 being likewise pivotally connected to the toggle lslide 40. The housing or slide 29 is, next placed in position over the levers with the thrust block 32 in proper position so that it can be convenientlv secured to the housing by Jibs such as 56 are then secured to each of the projecting blocks52, 53, 54, and 55, this operation being conveniently performed through the cored out'portions of the base plate 65, 66, 67, and 68. The lever 53 and its associated apparatus and the roller 6i may then be mounted in their relative positions and the cable 63 secured. to the arm 58. The toggle vise is now assembled for mounting on the bedplate 11 of the milling machine which is readily accomplished by securing the'base 10 thereof tothe bed plate 11 by means of the bolts and nuts 12 and 13 respectively. q i

When the vise 'has been thus mounted on the machine it is .first adjusted for the del sired amount of opening between the jawsI 18 and 26 of the vise when the toggle has been displaced in the position it is shown,

in in Fig. 2. This desired amount of open-.

he osition of the adjustingbar 22 on the bc t 20, said position being' readily changed by turning said bolt 20 which will movethe adjusting barA 22 either to the'right or0 left, upon the direction of notation-of The n'lovement'of -the adjusting 22 to the left increases the size of the opening between the jaws, and the movement to. the right decreases the size thereof. This flffollows.l directly from the fact that the pivoted depending `point 25 secured to the adjustment bar 22 is the stationary point of the toggle, and

said bolt.

' of the toggle vise, after whlch the operation ofthe mechanism may be changed for automatic or semi-automatic oper. tions.

Referring now to F igs. 6 and 7, 70 represents the column of the milling machine which carries the horizontal talble 71 on which the reciprocating bed 11 of the millingmachine is mounted. These drawings show a milling cutter 72 which is served with parts by toggle vises 73 and 74 attached to either end of the bed plate l1. As there indicated, the cables 63 of these toggle vises are connected to a stationary stud 5 on the machine, and as the bed 11 reciprocates to and fro, these cables 63 are alternately slackened and put under tension and the jaws of the vises open and close as hereinbefore described.

In a milling machine such as shown in Figs. 6 and 7, in which two vises are used, the direction of rotation of the cutter may be either reversed after each operation so that the articles will all be milled by the cutter cutting in the `same direction with respect to lthe fixed jaw of the vise, in which case -two cutters may be used, one for each vise; or the articles may be milled with one cutter rotating in the same direction for the articles contained in both vises. Ol)- viously the method of milling Ithese articles with a. pair of toggle vises, incorporating the invention herein described, may be accomplished in a large variety of ways without departing from the scope or spirit of the invention as hereinafter claimed.

Fig. 8 illustrates in diagrammatical form the method of mounting the vise on a mill-- ing machine for a longitudinal feed from the right-'hand side of the milling cutter. In this case the cable 63 is looped back to a stationary stop 76 located in back of the roller` 64. Vhen the vise is thus mounted on the machine the jaws thereof will be closed to hold the article to be operated upon when the vise is moving toward the left, at which time the article will .be operated on by the cutter 77. When the vise moves toward the right the cable 63 will be drawn taut and the vise will be opened.

Fig. 9 illustrates in dia ramma-tical form the method of mounting tie vise on a milling machine which is arran d for a vertical feed. 'In this case the ed stud 78, to which the cable 63 is attached, is mounted above the roller 64. on the vise. With the cable thus located it will be slackened when the vise moves upwardly, at which time the article to be-operated u on will be firml held between the jaws ci) the vise and wil be thus held as the article approaches the milling cutter 79. When the vise is moved down, the cable 63 will be drawn tautand the vise will open, so that the article operated on can be removed.

It will be evident from the various applications indicated in Figs. 6 to 9 inclusive that by properly locating` the fixed stud, to which the cable 63 is attached, the vise can be arranged for automatic operation for any desired movement of the movable table or 6 and 7 the operator can very readily feed articles to both vises as they reciprocate to and fro under the cutter, and because of the automatic action of the clamping means the speed and efficiency of this operation will be greatly increased.

Since the vise is adapted -for automatic,

Thus with a machine such as is depicted in Figs.

semi-automatic, or manual operation, its

utility is greatly enhanced, since it is thus capable for use with work which is extremely delicate and diiicult to perform, under which circumstances the manual or semiautomatic operation will be utilized, as well as for work of a rougher character, when the automatic operation of the vise can be used. The manual operation of the vise also facilitates the setting and adjustment there of for subsequent automatic operations. The vise is likewise designed for comparatively delicate adjustments of pressure between the jaws of the vise. This pressure can obviously be regulated by the position of the links ofthe toggle, the position of the links being controlled by the adjustin rod or bolt 20 and its associated adjusting har or block 23. Likewise since the vise is always closed automatically, any pressure for which it is adjusted will be applied with substantial uniformity vfor succeeding operations of the departing from its spirit and scope, as set fforth 'in' the following claims.
